Success Criteria

Requirements

Outcome

Landing Pad Footage

We have footage of all the requirements from GoPro and PiCam

  • Takeoff & landing in quad

  • Flight over pads at different altitudes

  • Landing pads on different terrains

  • Obstacles in the frame

    • Trees, bags, etc.

  • Grouped landing pads

  • Was the test successful? What was achieved (or not achieved)?

Telemetry

Data is sent and received from the aircraft

  • Testing datastream over RFD900x

    • Characterize data rate & packet loss at various altitudes & distances over different terrain

  • Test connection stability around obstacles and terrain

Video Transmission

Stable, low latency video is received from the aircraft that a pilot can use for flight

  • Testing stability with lots of communication interference

  • Test stability at various altitudes & distances over different terrain

  • Test connection stability around obstacles and terrain

Check temperatures

It’s not too hot

  • Is it really really hot after flight?

🗺️ Flight Plans

Location: field by the James Downey Wy and Laurelwood Dr intersection

Getting footage of 2 landing pads (One blue, one orange):

  • Put the landing pads 10m away from each other?? (not sure what the competition requirements are for how close they’ll be, hopefully that’s reasonable)

    • Place it in a grassy area on the field (not too close to the shrubs/trees)

  • Get footage of the drone flying over the landing pads at a constant-ish altitude

    • Until the landing pads would go out of sight in the footage

      • get footage at low, medium, high altitudes

  • Get footage of the drone flying upwards (just like flying up) over the two landing pads

    • Get footage of the drone landing on the blue landing pad

Get footage of one blue landing pad placed 2m, 5m, 10m away from shrub(s) or tree(s) (if you could get footage with different clusters of shrubs/trees, that would be great)

  • Fly around the landing pad and upwards/downwards to get footage of landing pad + the “obstacles” at different altitudes

📚 Flight Test Debrief

  • Flew successfully.

  • have ~ some ~ gopro footage.

  • RFD900 tested?

  • Briefing started at 11, last car returned at 14:45.

  • Footage may be corrupt?

  • Lost a picam.

  • FPV system did not work

  • Big Phoenix has some weird flight characteristics

  • minipix PDB smoked on last flight test. Big phoenix crashed.

  • Weather was not great.

  • Controls not clear. Big Judie crashed.

  • Walkie Talkies not working optimally. Only 2 working. No walkie talkie etiquette.

  • GoPro Battery died trying to get footage of landing pads on takeoff/landing. Picam also not attached at that point.

Flight Recaps

Judie & Landing pad footage

RFD 900 Comms

  • documentation soon

Phoenix Debug

  • phoenix unstable flight?

Operations Debrief

Weather Protection

  • a lot of stuff got wet!

Preparation

  • need more of that

  • Many things forgotten

Flightline Debrief

Safety / S.O.P / Emergency Procedures

  • safety procedures need to be followed.

  • we will update and revise our SOP → every member should read this.

  • Pilots should brief each other on terminology & controls before flying.

    • people not flying should follow instructions of pilots.

Flight Line Roles

  • Everyone should know what their task is to reduce the amount of “standing around”.

  • Being a “helping hand” is ok.

General Thoughts

  • modularity of nosecone - body is very nice .

  • pls stop cut hand open → conall

  • pretty damn cold - taim

  • cold - ayoung

Dealing with the cold

  • proper footwear (boots?)

  • try and have as much stuff put together as possible?

  • warming up in car?

  • Towels

  • No labels
